The most simplified version of the Python system command execution template

#!/usr/local/bin/python3
# -*- coding: utf-8 -*-
from subprocess import Popen, PIPE, STDOUT
#executed command
command='ls -l'. split()
proc=Popen(command, stdout=PIPE, stderr=PIPE, universal_newlines=True);
output, error = proc. communicate()

#display execution result
if(proc. poll()==0):
     print(output)
else:
     print("{} Error\n".format(error))

My most used Laravel passport directives

Laravel provides quite a lot of useful packages, such as Passport is one of them, when the website needs to set up its own OAuth2 authentication host, it really saves time and effort. Take this site as an example, because the front-end and back-end separation mechanisms are adopted (there are two different Laravel projects), and I verify them through the front-end WEB. Basically, I have many other different projects, and they all rely on OAuth2 provided by Laravel to handle cross-domain authentication.
